TEMPERATURE-EXOHANGING APPARATUS.

Specification of Letters Patent.

Patented April 14, I908.

Application filed December 31, 1904. Serial No. 239,063.

Apparatus, of which the following is a specii fication.

One object of the present invention is toprovide a simple, reliable andeflicient apparatus for causing two streams of fluid to exchange theirtemperatures, or in other words, to extract heat from one and impartitto the other.

Another object of the invention is to insure complete separation of thetwo streams of fluid under all conditions including such slight leakageas might occur at points where it is necessary to provide the apparatuswith parts made detachable for the purpose of cleaning its interior.

Another object of the invention is to eflect close caloric contact aswell as complete separation of the two circulating fluids whosetemperatures are to be exchanged in such manner as to insure acontinually changing relation of position between the circulating fluidstreams.

Another object of the invention is to provide for convenient andthorough cleansing of the apparatus.

Another object of the invention is to provide a compact mechanicalstructure such that its parts can be readily and economically assembled.I

The nature, characteristic features, and scope of my invention will bemore fully understood from the following description taken in connectionwith the accompanying drawings forming part hereof and in which Figure1, is a top or plan view with parts broken away illustrating apparatusembodying features of the invention. Fig. 2, is an 'elevational view ofthe apparatus in Fig. 1,

showin the apparatus with some of the cover plates removed. Fi 3, is atop or plan view of the apparatus Wit the top plate removed. Fig. 4, isa sectional view taken on the line 4-4, of Fig. 3, looking in thedirection of the arrows and with the intermediate parts of the apparatusexcept the part 17 b omitted. Figs. 5 and 6, are sectional views drawnto a reduced scale and taken on the lines 55 and 66 of Fig. 4. Fig. 7,isaview drawn to a reduced scale and illustrating in plan a detail, andFig. 8, is a sectional view illustrating a-modification.

As illustrated in the drawings the enerally rectangular structure ismade up 0% a series of adjacent chambers 1, 2, 3, 4, 5, 6, 7, etc. Eachchamber has one pair of its opposite examp e, in Fig. 5 the chamber 2,has its sides 8 and 9, normally open, and its sides 10 and 11, closed.The cover plates 12, 13, 14, 15 are removable, and it is of courseobvious that when they are removed, certain of the opposite sides of thechambers are open and others are closed, the purpose being to removethese plates when it is desired to clean the ap aratus and to have themin place when t 1e apparatus is in operation.

The construction of the chamber shown in Fig. 6, is substantially thesame as that shown in Fig. 5. The pair of op osite sides that are openare in Fig. 6, mar ed 10 and 11, and those that are closed are marked 8and 9. The chambers shown in Figs. 5 and 6, may be taken to besuccessive chambers as 2 and 3, of the series, so that the successivechambers are arranged cross-wise in respect to each other with theiropen ends accessible. For instance, the chambers of even number in theseries would have their 'open ends accessible from the sides 10 and 11,of the structure, while the chambers of odd number in the series wouldhave their open 'ends accessible from the sides 8 and 9, of thestructure as shown in Fig. 5.

At all sides of the structure there are ports a and b, of which thosethat are disposed at one pair of the opposite sides of the structureconnect alternate chambers. .For example, the chambers 1 and 3, areconnected by the port a, shown at the left in Fig. 4, and the chambers 3and 5, are connected at the right by the port I), and so on throughoutthe series. ssummg that m Fig. 4, the ports (I and I), are located atthe opposite sides, A and B, of the structure, there are exactly similarports at the other pair of opposite sides C and D, of the structure andthey connect the chambers 2, 4, 6, etc. This will be readily understoodby reference to Fig.2, which shows at the side A, arrows that 1ndicatethe ports which connect the chambers of odd number as 1, 3, etc, andwhich ports sides 0 en and the other pair closed. For' are shown in Fig.4.'- In Fig. 2, at the side C,

are arrows which show the ports that con which are fitted with inlet andoutlet connections'16 and 16", and 17 and 17 to be presently describedin detail, One stream of fluid, for example cold water, enters at 16",reaches the chamber 2, in a manner to be presently described, passesfrom chamber 2, to chamber 4, at the side C, of the structure. It thenpasses from chamber4, to chamber 6, at the side I) of the structure. Itthen passes from the chamber 6, to the eighth chamber in the series andso on throughout all the chambers of even number of the series untilfinally it arrives at the connection 17. From here it may go, forexample, to a sterilizer or to any other suitable piece of apparatuswhich performs the function of altering its temperature. If it shouldhappen to have gone to a sterilizer, it will return by way of theconnection 17 and will circulate through the chambers of odd number inthe series in a direction indicated by A-B, in Fig. 4, finally escapingby the connection 16. Thus there are two streams of liquid flowingthrough separate and distinct channels, one channel extending backwardsand forwards through the chambers of odd number in the series in thedirection A-B, and the other extending backwards and forwards throughthe chambers of even number in the series and in the direction C I). Inother words, these streams [low cross-wise of each other in adjacentchambers and effect between themselves an exchange of temperature. Eachof these streams of course flows along its appropriate chambers andthrough the ports which connect these chambers, so that the fluid ofeach stream is constantly disturbed. When the cover plates 12, 13, 14and 15, are removed, it is obvious that the various channels areaccessible, those of even number from both sides C & I), and those ,of

odd number from both sides A and B. The cover plates may be held toplace by bolting or otherwise securing them to thestructure and may befitted on their inner faces with suitable gaskets or packings but ifthey should leak a little no harm would be done.

- 1f fluid should leak at the righthand end in direction C-D,- and thecontrary of this is true.

The structure can be conveniently made in the following manner: 19, Fig.7, are plates each notched on its adjacent sides as at 20, for thepurpose ofproviding the ports which have been referred to. Instead ofnotching the plates 19, to form the ports, the lattermay compriserecesses 1) formed in the inte rior faces of the cover plates 12, 13, 14and 15 as is shown in Fig. 8. The plates 19, may be exceedingly thin andconstructed from sheet metal and they may be erforated at the cornersfor the passage of tlie bolts 21, which afford convenient means forassembling the parts of the structure as well as for supportmg them.-

22 and 23, are strips of which one 23, is notched as at 24, to providethe orts already described. T he stri s are s own as provided withopenings for t e passage of the- )olts 21. The strips are interposed inpairs between the plates 19 so as to form the chambers which have beendescribed and the pairs of strips are arranged in the respectivechainbers in cross-wise relation to the preceding and succeeding pairsso as to leaveopposite sides of the chambers open. The strips aresubstantially (so-extensive in length with the edges of the plates towhich they are adjacent. The strips are soldered to the adj acent platesor aproper joint is otherwise provided. At the top and bottom of thestructure one of the strips 25, Fig. 3, is made somewhat wide and isprovided with an opening as shown in said figure. This opening is alinedwith and made a continuation of the opening 16*, in the cover plate sothat the opening 16", communicates through the opening in the strip 25,with the chamber 2, whereas the opening 16, communicates with thechamber 1. At the bottom of the structure there is the same arrangementof com aratively wide strip and openings so'that a eseription of thebottom is unnecessary.

. It will be obvious to those skilled in the art to which the inventionrelates that modifications may be made in details Without departing fromthe spirit thereof, hence the invention is not limited further than theprior state of the art may require, but

Having thus described the-nature and objects of-my invention, what Iclaim as new and desire to secure by Letters Patent is:

1. A temperature exchanging device eonsisting of a self-sustainingstructure having a tinuous circuitous channels, and means for detachablyclam ing the covers to the structure, substantially as described.
